Christie Brinkley, a well-known model, is being up about how she's managed to look young for so long.

 The 63-year-old addressed the plastic surgery rumours in a recent interview by acknowledging that she had undergone anti-aging procedures,

including Ultherapy and Xeomin, which lift the skin on the neck and décolletage.

The blonde beauty told People, "I questioned if people would think I'm artificial and fake."

However, it is preferable to be truthful and state, "Yeah, this is what I do."

Christie acknowledges that she does want to feel well at her age even though she never wants to "look different."

"I'll be 64 soon. You could require a little something extra at some point.

I want to feel like I look as amazing as I feel when I look in the mirror," she admitted.

 "And if there is anything that can be done to make you feel better about yourself and more confident, then you feel like your face fits your spirit, and my spirit is exuberant and vivacious."

Christie additionally acknowledged obtaining fillers in a prior interview.
